1 Claim. 1

This invention relates to a toilet box outlet valve constructed in animproved manner so as to minimize danger of the valve not returning toits seat after each flushing operation.

In its broader aspect the present invention pertains to a toilet tankflushing valve the lower portion of which is constructed in such amanner as to receive a downward drag or pull by the outflowing waterwhich will increase as the valve nears its closed position, with theresult that the valve will close in a, quick accurately seated mannereven though it may not be suspended in accurate vertical alinement withthe valve seat with which it cooperates.

The invention may be embodied in an integral valve structure, or it maypertain to a valve construction which comprises a conventional elastictoilet tank valve and a separately made attachment applied to the lowerend portion of such a valve, said attachment functioning to cause thevalve to operate in the above mentioned improved manner. In this latteraspect the invention relates to a separately salable new article ofmanufacture.

It is not broadly new in the art to which this invention pertains tomodify a conventional buoyant, elastic toilet tank valve by constructingit with a downward extension to guide the valve to its seat; but aninvestigation of the prior art fails to disclose any valve structure ofthis kind which will afford an abutment efficiently to utilize theinertia of the outflowing water to produce a. definite downward pullupon the valve to cause it to seat in a better manner.

Accordingly it is an object of the present invention to provide a toilettank flushing valve with a downward extension which will present to theoutflowing water an upwardly facing shoulder or abutment which the waterwill strike against in such a manner as to accelerate the seating of thevalve, said extension at the same time aiding in guiding the valveaccurately to its seat.

Considered as an article of manufacture it is an object of the inventionto provide a generally cylindrical, elongated member having an upper endportion which can be inserted into the apertured lower end of aconventional buoyant elastic toilet tank valve, and which will safelyremain in the inserted position, where it will function to make thevalve operate in the improved manner herein already mentioned.

The lower end portion of the device may be considerably altered in shapewithout exceeding the scope of the claimed invention, provided that apart of said portion have an upwardly facing illustrates a preferred,reduced to practice ernbodiment of the invention,

Fig. 1 is a side elevation of a toilet valve constructed according tothe principles of the invention; shown associated with the outlet valveseat of the tank. In this view a part of the device is broken away todisclose an abutment carried thereby against which the outfiowing Waterstrikes to pull the valve toward its seat.

Fig. 2 is a view partly in side elevation, and partly in verticalmidsection on line 2-2 of Fig. 1, the valve seat being omitted.

Fig. 3 is a perspective view separately showing the attachment forconventional buoyant toilet tank valves, in which the device is embodiedwhen made as a new article of manufacture.

Fig. 4 is a transverse section looking downwardly from line 4-4 of Fig.2.

Referring in detail to the drawing therein is shown a conventionalelastic buoyant toilet valve body 1 of the doubly frusto-conical formwherein the larger ends of the frusto-conical portions abut each otherat the greatest diameter of the valve body. This hollow valve body isoperatively suspended by the axial rod 8 a fragment of which is shown inFig. 1 projecting from the upper end of said body, the lower end of saidbody having through it a circular central aperture.

As shown in Fig. 2, into the aforesaid apertured lower end of the hollowvalve body I is inserted the upper end portion 9 of a tubular member 50,the diameter of the inserted part 9 of said member being somewhatgreater than the normal diameter of the opening in the lower end of saidvalve body, so that an inturned annular lip ll in the elastic sheetmaterial of the body 1 results when the member ID is in its insertedposition. Owing to the considerable extent to which the r rubber has tobe stretched to insert the tubular part 9, the latter will be safelyheld in its inserted position by the gripping action of the surroundingrubber. As shown in Fig. 2 the inserted member [0 carries a peripheral,horizontal flange l2 which abuts the lower end portion of the valve body7 when said member [0 is inserted, as shown. This flange properly limitsthe extent to which said member Ill is inserted into the valve body 1.

Subjacent to said flange I2 the tubular member It has a downwardlytapered, imperforate portion 1 5 below the lower end of which it hasthrough it a plurality of longitudinal vertical slots l6, four of saidslots being present in the illustrated embodiment of the invention.Within the lower end of said tubular member In is an abutment formingcross wall, the upper face of which is shown on substantially a levelwith the lower ends of said slots, the latter being arranged in acircumferentially spaced apart series.

Preferably the valve structure which has been described will be mountedWithin the tank in such a position that the lower end portion of thetubular member [0 will never be lifted out of the passage through thevalve seat I9 shown in Fig. 1. A considerable portion of the stream ofWater which flows out through said valve seat (the internal diameter ofwhich is much greater than the outer diameter of the slotted part of themember IE), will enter the aforesaid slots [6 and will strike againstthe upwardly facing shoulder or abutment formed by the upper face of theclosure I1.

In doing this the outfiowing water will exert a downward pull ortraction upon the valve body I which will assist gravity to draw it toits seat in 4 as indicated in broken lines in the lower portion of Fig.1.

The non-elastic part of the structure may be.

made either of metal or of some suitable plastic material. The tubularpart of the device may be incorporated into the valve body I at the timeof manufacture as an integral portion thereof.

When said tubular par-t is used as 'an attachment it can be removed froma worn rubber valve and then attached to a new, unused one.

I claim:

As an article of manufacture, an elongated tubular member having anupper end portion crowdable into the open lower end portion of aconventional buoyant rubber toilet tank valve, said tubular memberhaving an external peripheral flange limiting the extent of itsinsertion into said valve, and having a closure cross wall at its lowerend and through its sides a plurality of vertical slots through whichthe outflowing water enters and exerts against said cross wall adownward pressure tending to close the valve.
